Eziriz .NET Reactor 是一个强大的代码保护和软件防盗版工具，完全由.NET框架编写。

.NET Reactor支持NET平台的软件许可系统，并支持NET程序集所有语言。

当.Net编译器编译你的C#或VB.NET程序时，程序员的程序并不会编译为原生的机器语言，而是编译成为了通用中间语言指令（CIL）。

CIL是介于源代码和本地代码的中间的语言，当你的程序运行，不是直接执行的机器代码，而是由.NET框架解释执行。

正因为如此，你的应用程序或库的源代码，可以很容易地复制。

CIL很容易被反编译，通过一些反编译工具，可以容易的将CIL反编译为C#或VB.NET源代码！显然，这种分发给最终用户的商业软件，很容易被你的竞争对手和不法分子所利用。
